The effect of nanocopper and mannan oligosaccharide supplementation on nutrient digestibility and performance in broiler chickens

Following the ban on the use of growth stimulant antibiotics in many countries, interest has arisen in finding a suitable alternative for antibiotics in poultry production.
The aim of this study was to investigate the effect of supplementation of two levels of nano-copper (0 and 100 mg/kg) and two levels of mannan oligosaccharide (0 or 1 g/kg) as natural growth stimulants on digestibility of nutrients and performance in broiler chicks.
At the end of the second week of breeding, 160 Cobb-500 broiler chicks were assigned in four treatment groups. For each treatment, four replicates (10 chicks per replicate) were considered. Experiment was conducted as a 2×2 factorial model in a completely randomized design.
No significant differences in digestibility of nutrients and growth performance between birds that ate the supplements with control group were observed (p>0.05).
Mannan oligosaccharides and nano-copper on growth performance and nutrient digestibility in broiler chicks had no significant effect. At the doses used, concomitant supplementation of copper and mannan oligosaccharide did not have a positive effect on traits that were studied in broilers.
